IMPROVEMENT IN SWING-S.

The Schedule referred to in these Letters Patent and making part of the s'ame.

To all whom it lmel/zj concern Be it known that I, WILLIAM H; ODEXATT, of Philadelphia, Pennsylvania, have invented an Improved Swing; and I do hereby' declare the following to be a full, clear, and exact description ofthe saine.

My invention consists of a swing, constructed, as fully described hereafter, so as to be readily oscillatcd, raised and lowered, and adjusted to form a seat or couch.

In order to enable others to make my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in Which- Figure I is a side View of my improved swing,

Figure 2, a front viewof the same; ,4

Figure 3, a portion ofiig. l, showing the seat of' the swing differently adjusted; auch v Figure 4, an inverted plan view of the seat.

Similar letters refer to similar parts throughout the several views.

The frame to which the swing is suspended, consists, inthe present instance, of abase, A, andposts, B, braced by rods, a, and connected together at the top by a crosspiece, 0.

To the under side of this cross-piece is secured a bar, F, having at its opposite ends double-hooked.shaped bearings, b, adapted to knife-edged projections, c, on

the upper ends of 'the rods H H, to which the seat of' the swing is secured. Y

The swing, when thus delicately suspended on knifeedge bearings, can be oscillated with little exertion in comparison with that required to operate swings Vsuspended by hooks and staples in the ordinary manner. Each of the rods H consists of two parts, c and j, one of which is arranged to slide upon the other, so

that the seat of the swing can be raised or lowered, and

adjusted to any required height.

The seat or chair of the swing consists of the seat proper, which is marked I, and of an adjustable back, J, and foot-board f.

A semicircular plate, fi, is secured to the lower end of each side of the back, J, and is arranged to slide upon a correspondingly-curved plate, j, secured to the side of the seat-projections Z on 'the latter plate, 4entering curved slots ofthe plate i, and securing the.v two together.

The back is thus hinged to and arranged to turn upon the seat I, the extreme positions, to which it is adjustable, being illustrated in-gs. l and 3, and the limit of these adjustments being determined by shoulders, m m', on the seat and back.

The intermediate positions to which the back can be adjusted and secured, are determined by pawls, p, which enter notches formed on the edges of the plates @'these pawls being hung to and operated simultaneously by a handled spring-rod, g, best observed in fig. 4.

he foot-board f is hung to thef'ont of the seat, and can be adjusted to any of the positions shown in the drawing, either permitted to hang down, or turned np,- so as to project above the seat, as seen in rig. 2, or it can be adjusted horizontally, so as to forni an extension of the scat, it being held up, while in the latterl position, by a button, s, iig. 4.

The swing is caused to oscillnte upon its bearings b b, by means of a cord, x, which is attached to a crossbar, t, on the rods H, and is passed over a pulleyyu, which is arranged to turn in the outer end of an arm,

` u', projecting from the bar F.

This cord can be operated from any convenient outside point, or by-a person on the seat of the swing, it being attached to the bar t, at a point close to the centre of oscillation, so that, as the cord follows the swinging motion of the seat, but little oi' it will be slaclrcned at any time.

When intended for in-door use, the frame A B C can be dispensed with, and the swing suspended directly from the ceiling ofthe room or apzutment in which it is placed, and the bar F inay, it' desired, be pivoted centrally, so that the swing can be turned, and caused to face in any direction.

Then the seat of the swing is adjusted, as seen in fig. 3, so as to form a reclining-couch, it will be found a very convenient substitute for the ordinary cradle, it

being protected on all sides by the arms y, and by the foot-board j", which can then be turned up.

When not in use', the swing can be readily detached from its bearings, and the two portions of the rods H caused to slide one within the other, the seat of the swing being then removed to a convenient place, and

occupying little. more room than an ordinary recliningchair.

I claim as my invention, and desireto secure by Lotters Patent- '1. The seat, with its 'rods f j", and slides H, in combination with the suspension-bars e c, on which the slides are zuljustablaand having openings to which are adapted detachable pins, all, substantially as described. j

2. "he bars e, col'iuected to the seat, and 'having knife-edge projections.adapted to bearings l), as dcscribed.

3. The seat, with its'adjustable back, in combination with the notched plate i. and spring-catchy, arranged and operating substantially as set forth.

'In testimony whereof, I have signed my name to this specification', in the presence of two subscribing witnesses.`
